Suppose you have done a regression analysis on 50 data

Suppose you have done a regression analysis on 50 data points in an attempt to find a linear connection between number of classes absent (x) and final exam score (y) for statistics students at State U. The correlation coefficient turned out to be .60.

a. Discuss what the correlation coefficient shows here.

b. If total variation in the 50 exam scores was 15,500, what must the explained variation have been?

c. Using your answer to part b, compute the unexplained variation and use it to produce the standard error of estimate, syx.
